It consists of a square, hexagonal or octagonal thin wall 1 substantially larger than the diameter 2 of the CD D to be placed on the centering device C, the recording face next to the wall 1 is protected by this wall, unrecorded The faces are not easily damaged, and the cover is considered unnecessary.

Fig. 2 is the example of the simplest case of the present invention, and it is stacked vertically on a shoulder 3, and the gap between the diameter 2 of CD in the shoulder and CD is less, and the profile 4 of shoulder is square, hexagonal or octagonal. Angular.

Figures 3 and 4 are examples of a single box which can also accommodate and hold labels E with supplementary information about CDs, these labels are viewed through the transparent wall 1, which is to be placed and protected by the inner conical surface 5 The recording surface of CD D is supported on the wall 1, and the conical inner surface fixes the periphery of the label by the conical bottom, and its profile 6 is square, hexagonal, preferably octagonal.

Figures 5 and 6 show examples of vertical stacking of the single flat cassettes of Figures 3 and 4 by means of a shoulder 8 or a ring 9 engaging in the top 10 of the cone 5.

Figures 7 and 8 represent the example of placing two CDs 15 and 16 with the recording surface facing the recording surface, which can be inserted or not, and the CD is centered and fixed on a cassette outside, and the profile 6 of the cassette is as follows: Square, hexagonal or octagonal. Since the recording surfaces of the CDs abut and protect each other, the case also has no CD-protecting walls. The CD is fastened to the cassette after elastically jumping over the small clamping projections 17 or 18 along the insertion side (section on the right). The sectional part on the left shows the shoulder 19 of the stop block cooperating with the boss 17 . Fig. 8 is a partial view showing that the fastening bosses 17 and 18 can be divided into several parts so as to clamp the CD.

Figures 9 and 10 are two examples of a single cassette comprising a simple centering device 20 (Fig. 9) and 21 (Fig. 10) which receives two CDs 22, 23 recording side-to-recording , you can insert pages or not insert pages. Like the case shown in Figure 7, the mouthpiece of the CD is snapped onto a boss 24 or 25 which is divided to facilitate clipping. Cassette 20, like cassette 21, has a central hole 26 for weight reduction. In FIG. 10, the clamping boss 24 is replaced by a shoulder 27 against which the CD 22 is pressed.

Figure 11 shows another example of a single cassette 30 comprising a simple centering device divided into two parts 31, 32 which receive two CDs 22, 23 with their recording sides facing their recording sides. The centering device 31 cooperates with a ring 33 via supplementary clamping devices 34, 35 in order to fix the CD, which is just fixed on the centering device with some play.

Figures 12 and 13 are any one of the boxes shown in Figures 9 to 11, the box has a vertically arranged support foot 38, the vertical foot includes a support base 39, the width of the support base is exactly one side of the octagon in Figure 3 width.

Figures 14 and 15 show an example of a dual cassette 40 in an open top view (Figure 14) and a cross-sectional view (Figure 15), respectively. The two parts 41, 42 of the box, octagonal in outline 6, each mount a CD clamped on its centering means C, and are connected to each other by means of a molded hinge 43 connecting them at one face , through points 44 cooperating with clamping holes 45, the hinge is able to close the two parts.

16, 17, 17A, 17B are examples of marking for CDs. A thin label 48 of plastic material is engaged in a chute 49 which is on the side of one of the faces 50 of the cassette in the case of vertical sorting. This label can contain category-specific information. Figures 17A and 17B show a supplementary example of identifying individual CD families, this example comprising single-color sticks 52, two-color sticks or three-color sticks which engage in a hole 53 opened in a side 54 of a face 6 of the case.

Figures 18 and 19 show examples of single cassettes 57 and 58 which can accommodate two CDs and four CDs. The example of the box shown in Figure 18 is to lay down a CD D1 and a CD D2 from each side wall 59 thereof, and each CD holder is clamped on the corresponding centering device C1, C2. The cassette includes a double shoulder 60 which may not be tapered if no label is used since the label does not need to be visible. When a CD uses a label, the label gives supplementary information about the content of the CD, where the main information is written on the outer, visible, non-recording side.

Fig. 19 shows an example of a single box 58, from each side of its wall 64 two CDs are placed facing each other, with or without interleaving between them. Their central positioning devices C3, C4 can be slightly longer than the central positioning devices C1, C2, so as to be able to clamp two CDs at the same time. The method on the CD pine card is the same as that on the other boxes. The thickness of the double shoulders 65 is the same as that of the central positioning means so that they can be arranged vertically or stacked vertically.

Figures 20 and 21 are examples of double cassettes 68, 69 which can hold three CDs or four CDs. These cassettes are similar to those in FIGS. 14 and 15 . Fig. 20 represents three CD D1, D2, the example of the double box of D3, there is D1 on the left part 71, two of D2, a D3 on the right part 72. The left part 71 has a thicker shoulder 70, and the centering device C3 for two CDs is slightly thicker than the right part 72 for only one CD. The two parts 71 rotate about the molded hinge 43 . Labels can be provided on the wall of the right part 72, and a page can be inserted between two CDs in the left part 71. When the case is opened, the unrecorded sides of the three CDs are visible, ie the outer side and the other two sides can be seen.

Figure 21 shows a double cassette 69 with two symmetrical parts 71, 75, each of which mounts two CDs D1, D2, and D3, D4 with recording faces facing recording faces, thus passing transparency from the outside and from the inside when opening the cassette These four unrecorded faces with information can be seen.

22-26 show cross-sectional views of a CD centering device. FIG. 22 is an example of a centering device 78 . The support wall thickness 79 of the recording surface of the CD or DVD on the centering device is at least reduced by half 80, so that it deforms elastically. The clamping shoulder 81 is slightly tapered so as to elastically deform when the CD is positioned. When pressing the middle of the centering means along arrow 82 , the wall deforms along dotted line 83 , the purpose of which is to reduce the diameter of shoulder 81 . If the outside of the cassette is reversed at the same time, the CD disengages its centering device. A second centering device 84 identical to the first centering device is heat welded at 85 against the first centering device.

23A and 23B are mainly examples of a cassette with a centering device-ejector for mounting DVD-like laser discs. The cassette includes the same centering device as in Figure 22, but an ejector that is elastically deformable is added to the positioning device, and when pressure is applied to the center of the centering device, the CD can be lifted. Ejection can be achieved in many ways, and can be achieved with at least three soft elastic nubs 85, which are glued in the bottom of the corresponding notch 86, expanding the sides of the notch, so that when the DVD or CD holder is inserted into the When onto the shoulder 81 of the centering device, the nub can be squeezed. The free end of small piece 85 is hemispherical, and its height is identical with that of central positioning device, can replace small piece 85 with elastic small ball B (Fig. 23B), small ball is glued in the corresponding small chamber; A molded sheet 87 (right side of Figures 23A and 23B), or sheet metal L, engages the sheet metal in a chute (Figure 23B) and sticks it tight. When pressure is applied to the middle 82 of the centering means, nubs 85, balls or tabs 87 lift up, disengaging the DVD from its centering means.

Fig. 24 is used for laying the CD D1 of two recording surfaces facing recording surface, the example of centering device 88 of D2. Its shape is similar to that of the centering device of Fig. 22, but taller, because it will place and fix two CDs instead of one, so the slope of the cone 89 will be smaller. Clip the two CDs in the same way as in Figure 22. In order to place one or two CDs on the other side of the wall 1, a centering device 90 for placing one or two CDs is reheat welded against the first centering device.

Fig. 25 is the example that is used for the central positioning device 92 of CD; Under the premise of keeping center 95, just can make this central positioning device have flexibility by dividing the face 93 of clamping cone with knife groove 94 into several parts, Gripping pressure acts on the center. To accommodate two CDs, add the thickness of one CD to the height of the centering device. For other aspects of the centering means, a second centering means may be heat welded on the other side of the cassette.

Figure 26 is another example of a centering device 98 on a shoulder 99 to which a ring 100 having a diameter slightly larger than the diameter of the center hole of the CD is bonded to produce a small holding pressure on the CD. The CD can be ejected by pushing the rear portion of the CD support surface through the hole 101 .

Figures 27 and 28 are examples of boxes with CDs arranged vertically or at a slight inclination, which can be placed flat or vertically. The cross-sectional shape of the box corresponds to that of the octagonal box. The box consists of two halves, an opaque or translucent lower part 110 and a transparent upper part 111 . Between the two halves 110 , 111 there is a clip replenishment device 112 . The two ends of the two halves are covered by other boxes towards the outside of the clamping device, that is, one side is a male box 113 and the other side is a female box 114 . In order to be able to visually see the unmarked CDs, the case can be tilted about 15 degrees, a gap can be left between the outside of the case and the inside of the case, and the angle of some of the faces 115, 116 can be slightly increased.

Figures 29 and 30 are front and top cross-sectional views of 2, 4 or 8 CD flexible sheets laid flat. The thin sheet 118 is a transparent plastic material, and there are brace plates 120, 121 facing heat welding up and down, these plates can combine the thin sheet into a package (Fig. 31), and the thin sheet also has a section that can be bent for observation 119 and rigid plates 123, 124, 125 thermally welded up and down the length and 126, 127, 128 thermally welded along the width to define the space for the CD. Each CD holder is snapped onto a centering device 130, shown in section in Figure 30, which is heat welded to the upper and lower sides of the sheet. The centering device comprises a thin wall 131 bordered by a support portion 132 tapered to a diameter allowing easy fixation in the center hole of the CD, and a small bevel 133 of the inlet. The milling part 134 makes the tooth 135 elastically deformable, thereby facilitating clamping. As long as the central part 136 is heat-welded on the sheet, the flexibility of the clamping tooth can be maintained.

Fig. 31 is the example of laying sheet 118 flatly, and sheet is combined on the folder 140 that a thermoplastic material is made, folder comprises a bottom 141; The bottom thickness is at least 1.5-2mm, a back 142; A molded hinge 143 is connected to the bottom and a cover 144; the cover is connected to the back 142 by a second hinge 145. The folder is closed by a front 146 which is connected to the bottom by another molded hinge 147 . The free end of a strong fabric band 148 bonded to the front 146 includes a band 149 of "grab" material which, when it abuts the cover 144 against the upper sheet 118, rests on the other " The belt 150 made of "grab" material stays on, which prevents all CDs from coming into contact with dust. Folders made of thermoplastic material can be covered with upholstery fabric.
